After the OEM tail light decided to fall off on a long ride (plastic thumb-nuts BMW? really?), I decided to move to a universal Koso Infinity LED Tail light (https://kosonorthamerica.com/product/infinity-led-taillight-red/) for the sole reason that it was the cheapest tail light on Revzilla at the time. The problem is that the mounts on the bike are at a ~25 degree angle sloping downwards, so a naive perpendicular mount ends up illuminating the ground more than your tail (and makes the license plate light borderline useless.)
This has holes for some M6 bolts (I used some 70mm bolts, definitely too long. I'd say 40-50mm is probably safe.) It also has a cutout for the cables that come straight out of the back of the Koso light. There are two zip-tie loops on the bottom for cable management, feel free to try a little harder than I did when it comes to actually using them.
I'd STRONGLY RECOMMEND a liberal application of threadlocker on all relevant fasteners (or get nylock nuts if you can.)
I did a test print at draft quality before doing some tweaks and honestly it was pretty strong, but I did beef it up to 4 perimeters, ~20% gyroid infill, and the .20mm structural profile for the final part. All prints were in black Overture PETG and printed on a Prusa Mini.
